For all but a few locations, the latitude and longitude listed were identical in the two sources, but a few locations were listed in only one of the two documents, or were listed with very slightly different coordinates in the two sources. In the later case, I averaged the differing coordinates; coincidentally, in all such cases the difference between the two sources was either 1, 3 or 5 minutes, so the average (shown here) ends in ".5" minutes.

The numbers in red are values which I calculated from the other data.

The station names are links to NOAA's MSL trend line graphs and notes for each station.
However, NOAA only recalculates the MSL trend lines every 8-10 years, so I've also
included links to newer data for each station. For the latest available data click
on [2] (for NOAA-maintained stations) or [3] (for other PSMSL stations).

Note: The portion of this web page preceding the red line is in Microsoft Excel 2000
HTML spreadsheet format. So if you want to load the data into a spreadsheet you can just
load the web page into Excel (version 2000 or later). Doing so will scramble the text
after the red line, but the data and formulas above the red line will load correctly, and
the numbers will be represented with greater precision than is shown on the web page.

† The column entitled "Total MSL change (cm)" is
simply the calculated product of the "MSL Trend" (divided by 10 to convert mm to
cm) and "Year Range" columns. Since the MSL Trend is determined (by NOAA) by
linear smoothing, and there are substantial year-to-year fluctuations in MSL at most
locations, the "Total MSL change" is not precisely the difference between the First Year
MSL and the Last Year MSL. Rather, it is an intermediate value used to calculate the
"average2" MSL Trend (in which each station-year is weighted equally; that is, in which
each measurement location is weighted according to how long it was in operation).
